Background

Function
PKD2 encodes polycystin-2/TRPP2, a six-transmembrane, non-selective cation channel that localizes to the primary cilium, plasma membrane, and endoplasmic reticulum[1][2]. Mechanistically, PKD2 supports ciliary ion-channel activity in renal collecting duct epithelium, where the native channel conducts K+ and Na+ and is sensitized by high intraciliary Ca2+[1]. Through interaction with PKD1, PKD2 contributes to a receptor-ion-channel complex that links extracellular cues to Ca2+-dependent signaling, including WNT/Ca2+ responses[3]. In disease models, loss of PKD2 or exclusion of channel-functional polycystin-2 from cilia promotes renal cystogenesis, supporting a cilia-centered mechanism in autosomal dominant polycystic kidney disease[1][4]. Compared with PKD1, PKD2 provides the required ciliary channel subunit, while PKD1 can confer distinct channel properties within the PKD1-PKD2 complex[1][5]. Compared with PKD2L1, PKD2 shows different ciliary ion selectivity, because PKD2L1-containing channels preferentially conduct Ca2+[1][6]. For experimental applications, direct ciliary electrophysiology and heterologous ciliary expression provide practical systems for evaluating PKD2 variants and channel behavior[1]. Pharmacological work should distinguish PKD2 from associated subunits, because pregnenolone sulfate and isosakuranetin modulate a TRPM3-dependent TRPP2 ciliary channel rather than proving PKD2-specific agonism or inhibition[7].

Isoforms & Post-Translational Modification
Q9BZL6 has 3 isomers: Q9BZL6-1: 96722 Da (predicted); Q9BZL6-2: 80115 Da (predicted); Q9BZL6-3: 97743 Da (predicted).
Phosphorylation of Ser-876 correlates with the activation status of the kinase (PubMed:11062248). Ser-706 or/and Ser-710 are probably phosphorylated by PKC (PubMed:12058027, PubMed:28428613). Phosphorylation at Ser-244 by CSNK1D and CSNK1E promotes nuclear localization and substrate targeting (PubMed:17962809). Phosphorylation at Ser-244, Ser-706 and Ser-710 is required for nuclear localization (PubMed:17962809). Phosphorylated at Tyr-438 by ABL1 in response to oxidative stress (PubMed:15604256). Phosphorylated at Tyr-717 by ABL1 specifically in response to oxidative stress; requires prior phosphorylation at Ser-706 or/and Ser-710 (PubMed:28428613) -
Subunit
Interacts (via C-terminus) with LCK (PubMed:19192391). Interacts (via N-terminal AP-rich region) with CIB1 isoform 2 (PubMed:23503467). Interacts (via N-terminus and zing-finger domain 1 and 2) with PRKCD in response to oxidative stress; the interaction is independent of PRKD2 tyrosine phosphorylation (PubMed:28428613)
